Deploy the kinesalite helm chart on Kubernetes

Question

Pulumi · Accepted Answer

Deploying a Helm chart on Kubernetes with Pulumi involves several steps. We'll use the `kubernetes.helm.v3.Chart` resource to manage the deployment of the kinesalite Helm chart. Kinesalite is a lightweight implementation of Amazon Kinesis that runs as a standalone service, often used for local testing.

Here's what you need to do step by step:

1. **Set up a Kubernetes cluster**: Before deploying the Helm chart, you need a running Kubernetes cluster. This could be a cluster on any cloud provider or a local one like Minikube or Docker Desktop. Make sure your `kubectl` is configured to interact with this cluster.

2. **Install Pulumi**: If you haven't already, [install Pulumi](https://www.pulumi.com/docs/get-started/install/) and [set up your cloud provider](https://www.pulumi.com/docs/intro/cloud-providers/).

3. **Create a Pulumi project**: Create a new Pulumi project using your preferred language, but here we will use TypeScript.

4. **Create a new Kubernetes `Chart` resource**: Use `kubernetes.helm.v3.Chart` to deploy the kinesalite Helm chart to your Kubernetes cluster.

5. **Configure the release**: Typically, you need the Helm chart name and optionally the repository URL where the chart is located. If `kinesalite` is not in the default Helm chart repository, you will have to specify the repository. You can also specify other values to customize the release.

6. **Run Pulumi**: With your Pulumi program written, run `pulumi up` to deploy the Helm chart to your Kubernetes cluster.

Let's write a Pulumi program to deploy the kinesalite Helm chart:

```typescript
import * as k8s from "@pulumi/kubernetes";

// A Pulumi program to deploy the kinesalite Helm chart on a Kubernetes cluster.
const kinesaliteChart = new k8s.helm.v3.Chart("kinesalite", {
    // Replace `CHART_NAME` with the actual Helm chart name for kinesalite.
    // If there's a specific repository for the kinesalite Helm chart, provide the `repo` property
    // with the URL of that Helm repository.
    chart: "CHART_NAME",
    // Specify the namespace where the Helm chart will be deployed,
    // if not specified, it will be deployed in the default namespace.
    namespace: "kinesalite-namespace",
    // If kinesalite requires some specific configurations, you can specify them in the `values`
    // For example, if you need to set the replica count and some other property:
    values: {
        replicaCount: 1,
        someOtherProperty: "some value",
    },
    // If you have a custom repository, uncomment the next line and provide the repository URL.
    // repo: "YOUR_CUSTOM_HELM_REPO_URL",
});

// To get the status of the deployment, you can export it.
// This will print out the status after `pulumi up` is successful.
export const kinesaliteStatus = kinesaliteChart.status;

// Run `pulumi up` to deploy this chart to your Kubernetes cluster.
```

In this program, replace `CHART_NAME` with the actual name of the kinesalite Helm chart and provide values as per the chart's requirement. If you know the repository URL of the kinesalite Helm chart, replace `YOUR_CUSTOM_HELM_REPO_URL` with that URL. The `namespace` is set to `kinesalite-namespace`, but you can change this to whatever namespace you prefer.

After writing and saving your program, navigate to the directory of the Pulumi project in your terminal and execute the `pulumi up` command to deploy the kinesalite Helm chart to your Kubernetes cluster. Pulumi will show you a preview of the changes and prompt you to approve them before making any changes to your infrastructure.
